Diagram D represent how $3$ fishing rods must be positioned to ensure effective movement. Diagram $E$ is a sketch of diagram $D.$ Bhat$(A)C=xD,E$ and $F$ are the midpoints of the different circles. $GH$ is a common tangent on circles at point $D$ and $E.$ IJ is a common tangent on circles at point $D$ and $F.BD=DC=pcm$ radii, Radius $EK=qcm$ and radius $LF=qcm.$ and $B\frac{C}{\frac{?}{?}}EF.$ MDN$,$ EBD and FCD are straight lines. $7\mathrm{.}1.$ Determine hat$(E)$ in terms of
